Solar Panel Cleaning: “Do my solar panels need to be cleaned?”

Friday September 30, 2022 comments

Solar energy is the most abundant renewable energy source available to us. Averaging 237 days of sunshine, Florida, aptly nicknamed the Sunshine State, is one of the most popular places to find solar panels installed on residential homes. In fact, solar panels power roughly 100,000 Florida homes, and that number is rising. Solar panels are a fantastic way to harness the sun’s power to save on bills, while simultaneously supporting a clean environment.


There are many benefits to going solar:

  • It is pollution-free
  • Renewable and clean
  • Available every day of the year
  • Can be used to power homes, cars, and heat water
  • Safer than traditional electrical

If you are one of the many taking advantage of this resource, you may have wondered, “Do my solar panels need to be cleaned?”

The answer is a resounding, “YES.”

You should have your panels cleaned every six months to a year. This will optimize your solar system’s overall functionality and energy output, while also keeping your panels protected from harm caused by the elements.

Bird droppings, dust, salt, calcium deposits, and sand all hinder solar panels from operating at their full potential. Grime and residue build up on the panels over time, decreasing the solar cell productivity. Even worse, ignoring routine maintenance can destroy the cells themselves. Solar cells on panels covered or encrusted with dirt will heat to an extent that results in damage, reducing their effectiveness. The frequent Florida rains are definitely a help in keeping your panels free from caked-on crud, but rainstorms don’t cure all. Even after a heavy downpour, your solar panels may suffer from the salt and calcium deposits left behind. Just as regular maintenance is required for the other outdoor features of your home, a thorough cleaning will keep your panels protected and functioning at optimal capacity.

Many homeowners think they can easily wash their solar system on their own, but cleaning your own panels can be dangerous and is highly discouraged. Climbing up on top of your roof and using a little elbow grease may save you some money, but it is also a threat to your safety and the safety of your panels. Scrubbing your solar panels with a rag or sponge may result in scratching, and power sprayers can be downright disastrous. Even the sediment in regular water can cause calcium build-up and negate the entire purpose of the cleaning. When paired with a slippery, wet roof, the risk of doing it yourself can greatly outweigh the reward. If you want the job done properly, not to mention safely, call in a professional.
